TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 726,560, dated April28, 1903.

Application filed April 23, 190i. Serial No. 57,051. (No model.)

To all whom, it may concern: Be it known that I, JACOB E. NEAHR, acitizen of the United States, residing at Buffalo, Erie county, NewYork, have invented oer tain new and useful Improvements in'Type-IVriting Machines, of which the following is a specification.

My invention relates to type-writing machines; and the object of thesaid invention to is to provide a simple and efficient multipletype-writing machine wherein the separate machines are located at remotepoints and the movement imparted to the parts of one writing-machinewill be transmitted through 1 5 mechanical means to the correspondingparts of another or of other writing-machines.

In the accompanying drawings,wherein like reference characters indicatecorresponding parts in the various views, Figure I is a side viewshowing two type-writing machines with intermediate connectionsconstructed in a'c cordance with my invention. certain parts are shownin section and other parts are omitted for the purpose of clearerillustration. Fig. II is a diagrammatic side view of the type movementsand the intermediate connections between the same. Fig. III is a viewwhich corresponds to Fig. I, the view showing the mechanism forreturning the carriage and operating the line-spacing feed. Theconnections between the other parts are omitted to avoid confusion inthe illustration. Fig. IV is a front view, partly in section, of theso-called operators machine. Fig. V is a diagrammatic side view of thetabulating devices and the connections between the same.

I have illustrated my invention applied to the well-known Underwoodtype-writing machine, though it shouldbe understood that the purpose ofthe invention may be carried out with the aid of other type-writingmachines.

Referring particularly to Figs. I and II of the drawings, it will beobserved two Underwood type-writing machines A and B are located atpoints remote one from another. The type-writing machine A, I will referto as an exhibit machine and the machine B as an operators machine. Theexhibit machine is placed upon a suitable support or pedestal a, whichis preferably hollow, so as In this View to hide from View the variousmechanical connections which pass through the pedestal and which areintended to operate the working parts. The operators machine may besupported upon a suitable desk I), which is likewise preferably inclosedat the lower portion,

so as tohide from view the connections between the machines.

While I have illustrated in Figs. land II but a single type-bar movementfor each machine and the connections between the movements,

it will be understood that the usual number of type-bar movements areemployed in each ma- 6 chine and that the corresponding movements in thevarious machines employed are con- 'nected in the manner illustrated.Thus each of the'key-levers -1 of the operators machine 1 is operativelyconnected to a link 2, which 00- operates with a type-bar 3. .Each ofthe typebar movements in the exhibit machine or machines is constructedin the same manner. To

.each key-lever of the operators machine is connected a depending link4, which has its opposite end pivoted to an angle-lever 5, Y which inturn is pivoted to a fixed bracket 6. The opposite end of theangle-lever 5 is connected to a Wire or ligament 7, which, as indicatedin Fig.1, may be made in two parts and provided with turnbuckle 8. Theopposite end of this wire is connected to one arm of an angle-lever 9,pivoted to a fixed bracket 10, preferably secured beneath the flooringC. The other arm of the angle-lever 9 is connected to a wire 11, whichmay likewise be made in two parts and provided with a turnbuckle 12. Theopposite end of the wire 11 is connected to one arm of an anglelever 13,which corresponds to the angle-leo ver 9, except that it is positionedoppositely from thelever 9, so as to effect a downward pull upon thewire 14, which is connected to the second arm of said lever 13." Thewire 14 may likewise be made up of separate pieces 5 united by aturnbuckle 15, and it has its opposite end connected to the key-lever ofthe exhibit machine which corresponds to'that of the operators machine,which is-operatively connected therewiththat is to say, the keylovers inthe various machines which are operative to print the same charactersare united.

From the foregoing it will be seen that a depression of any key-leverupon the opera tors machine will cause a like movement to be transmittedto the corresponding key-1e ver of the exhibit machine or exhibitmachines, if several are employed.

The space-bars 16 of the different machines (see Fig. IV) may beconnected in the same manner as the key-levers, except the angularlever, which corresponds to the lever 13 of the connections between thekey-levers, has one long arm and one short arm, as suggested at theleft-hand side of Fig. V. The purpose of. this specific construction isto increase the throw of the operating-lever on the exhibit machine inorder to insure a correct operation of the spacing mechanism.

The tabulating device illustrated diagrammatically in Fig.V is the sameas that shown in the Manning patent, No. 609,517, dated August 23, 1898,and is sufficiently illustrated in the drawings to arrive at anunderstanding thereof.

It will be understood that the various portions of each tabulatingmechanism proper shown in Fig. V are carried by the framing of thecooperating machine and that an operation of the tabulating mechanismwill cause the feed mechanism of each machine to be disengaged to permitthe carriage to move freely to the point where the carriage is to bearrested and that the same movement which accomplishes this resultinterposes tabulating-stops carried by the framing of the machines inthe path of the cooperating tabulating-stops on the carriages. Thus uponreference to Fig. V it will be seen that the tabulating-key 17 of eachdevice is carried at the free end of the key-lever 18, which is pivotedatitsinnerend,asindicatedatlf). Eachkeylever 18 has anupwardly-projecting arm 20, which cooperates with the lower end of alever 21, that is pivoted to the framing of the machine or to a fixedpoint, as indicated at 22. The upper end of the lever 21 is slotted at23 to receive a pin 24, carried by a depending arm 25, that is securedto a horizontallydisposed rock-shaft 26. This rock-shaft 26 carries oneor more tabulating-stops 27, that are preferably adjustable in thedirection of the length of the rock-shaft. The rock-shaft likewisecarries an arm 28, which projects inwardly therefrom and is adapted tocooperate with a pin 29, secured to one of the feeddogs 30 31. Thetabulating-key 17 of the operators machine is connected to a dependinglink 32, which in turn is pivoted to one arm of an angular lever 33.This angle-lever is pivoted at 34 to a fixed point-such, for instance,as a bracket 35, which corresponds to the bracket 6 shown in Fig. I. Theopposite end of this lever 33 is connected to a wire 36, thatcorresponds to the wire 7 shown in Fig. I. In fact, the entireconnection between one tabulating-key and another is the same as theconnection between the key-levers 1, except that one arm of theangle-lever 37 is longer than the other and is different in this respectfrom the corresponding lever13 of the key-lever connections. The purposein elongating one arm of the lever 37 is to increase the throw of thetabulatinglever on the exhibit machine in order to assure a correctoperation of the tabulator.

From the foregoing description it will be seen that a depression of theoperators tabulating-key will cause the tabulat-ing-stop 27 on theoperators machine to be rocked in the direction of the arrow in Fig. Vto interpose it in the path of a cooperating stop on the carriage of themachine. This same movement will cause the arm 28 to bear upon the pin29, thus disengaging the feed-dogs from the rack on the carriage inorder to release the carriage. The motion imparted to the tabulating-keyof the operators machine will be effective through the intermediateconnections to bring about the same movement of the corresponding partsin the exhibit machine.

I will next refer to the mechanism for restoring the carriages andelfecting a linespacing of the platens. Referring particularly to Figs.III and IV, it will he noted that a bracket 38 pivotally supports anoperatinghandle 39, which is connected to a wheel 40, that is providedwith an eye 41. A flexible connection 42 passes loosely through this eyeand the connection may be made in two or more parts which are united byturnbuckles, as indicated at 43. Reference being had to Fig. IV, it willbe seen that one end of the flexible connection is connected, asindicated at 44, to the lever 45, which turns the platen 4Q forline-spacing. The flexible connection 42 passes along the front of thecarriage-frame and under the front bar thereof and ordinarily cannot beseen. On the right-hand side of the framing of the machine is supporteda small pulley 47, over which the connection passes. The connection 42next passes freely through the eye 41 and thence over the pulley 48.From the pulley 48 the connection 42 passes down through the inside ofthe desk and over pulleys 49 and 50, up through the pedestal a, over thepulley 51 on the exhibit machine, and over to the left-hand side of thecarriage,

where connection is made with the lever.

which turns the platen in the same manner as in the operators machine.Thus one end of the connection 42 is secured to the platenturning lever45 on the operators machine, whereas the other end is connected in alike manner to a corresponding lever on the exhibit machine. Whenpressure is exerted upon the connection 42 intermediate of the endsthereof, it not only tends to turn the platens of both the machines,butafter the levers 45 reach the limit of their movement and the platenshave been turned the carriages will be moved from left to right, so astorestore both carriages to their positions, each to begin a new line. Asingle upward pull upon the handle 39 on the operators machine willeffect this turning of the platens and the restoration of the carriagein both machines. By reason of the fact that the connection 42 passesloosely through the eye ll no harm can-result from moving the carriageof either machine by hand without resorting to the handle 39. Thus, forinstance, if we suppose that the carriage of one machine is farthertoward the left than the other then an upward movement of the handlewill first take up the slack in the connection 42. When the slack istaken up, the pressure on both carriages through the connection 42 willbe substantially the same. If one carriage reaches the margin-stopbefore the other, then it will be stopped and the connection will slipthrough the eye ll as the other carriage continues to move back to theright and both carriages will again be in a position to start a newline. It will be observed that by constructing the parts in the mannerdescribed the weight of the handle 39 and the parts connected theretowill not be opposed to the feed of the carriage.

The multiple type-writing organism forming the subject-matter of mypresent invention may be used for a variety of purposes. Thus, forinstance, aside from the fact that the machine multiplies the capacityof a single machine as to the number of copies produced, the so-calledexhibit machine may be placed in a window or other public place and willform an attractive advertisement, inasmuch as the machine will writeWithin sight without any visible means for moving the parts. Additionalinterest is presented when something is written upon the machine withinthe view of those examining it that is applicable to them. Heretofore ithas been customary to place an operator at the machine in the window orother public place; butthis method of showing the working qualitics ofthe machine is in no sense so attractive as a machine which is writingintelligent sentences apparently of its own accord.

It will be understood that the operators machine may be placed at asufficiently-remote distance from the exhibit machine so as not to drawsuspicion to the fact that one operator moves both machines. Again, theoperators machine may be kept out of view of those examining the exhibitmachine, though there is little exposed on either machine which wouldlead the ordinary observer to believe that the operation of one machinecontrolled the other.

While I have described with some detail one form of mechanism embodyingmy invention, it should be understood that various changes may be madewithoutdeparting from the spirit of my invention and in order to adaptthe invention to different type-writing machines.

Having described my invention, what I claim, and desire to secure byLetters Patent, is

1. The combination of a plurality of typewriting machines withtransmitting or connecting mechanism extending from-a movable part ofone machine to the corresponding part of the other machine, saidconnecting mechanism comprising two main bellcrank levers .eaeh arrangedadjacent to one i of the machines and mounted to turn about axestransverse to the connecting-line of the machines, each of saidbell-crank levers having one of its members projected inwardly towardthe other bell-crank lever, a tension member connecting the othermembers of said bell-crank levers, another tension member connecting thein-wardlyeprojecting member of one of said bell-crank levers with thesaid part of the adjacent machine, a third, auxiliary, bell crank leverlocated at the other machine and connected at one side of its fulcrumwith the said part of said other machine, and a tension member extendingfrom said third lever at the opposite side of its fulcrum, to theinwardly-projected member of the other main bell-crank lever locatedadjacent to the same machine.

2. The combination of a plurality of type- Writing machines havingspacing-levers for turning their platens, with a connection from thespacing-lever of one machine to that of the other machine, and anoperating device connected with said connection to first turn theplatens and then shift the carriages in the same direction.
